Acorn technical documents

Available here are various documents on Acorn computers that I've collected.
Most date from the early days of the Archimedes, and some were posted on SID,
Acorn's now defunct bulletin board (announcement). If the original document is dated, the
date is shown in brackets next to the document title. However, this may be
their release date and not the date of creation. Some are culled from news
- the full headers are included so you can look the relevant threads up on
Google Groups if necessary.

On most of these documents there is no indication of author or copyright
holder. I seek no gain of any kind from making these documents available,
and if I informed that I am breaking copyright I shall remove any pages at the first
opportunity. None of the news articles have X-No-Archive set - if you'd
like me to remove one of your articles, let me know.
All information is provided in good faith, but I cannot make any
guarantees as to its accuracy.

This page is designed to complement Robin Watts'
Documentation on Acorn Computers pages - he was too busy to incorporate them
into his site when I contacted him, so these two sites should be used side by
side. I have tried to eliminate any duplicate material in the list on this page, but if you find any,
please let me know.

Much of the material here is taken from Usenet, Arcade BBS, old public domain discs,
contributors and other sources. If you have any more material like this,
please do not hesitate to contact me (theo [at@] markettos.org.uk) - it will doubtless be of
use to someone.

Browse the directory structure - the whole archive is here, including those that are duplicates of those on Robin's site. There are more than those listed below.

Acorn Unix Econet Device Driver and Network
Device - notes
on RISC-iX's network driver, particular how it handles transmission of
packets Econet packets over Ethernet (later AUN uses the same strategy). Abstract
says: "This document describes a device driver which controls the Acorn
Econet and a Unix Networking Device which uses Econet, in Acorn's
implementation of Unix 4.3BSD, from both the user's view and from that of a
programmer who wishes to understand and maintain the code." (1988/9)

(zip archive,
directory structure,
index). This is a
collection of various interesting documents sent to Usenet (hardware and
software info). Individual documents are linked separately on this page. Also includes:

Eureka 1, 2, 3 This was an electronic magazine run by Dave Walker.
Useful hints (except those involving direct access to VIDC registers !)
and hardware info (Podule interfacing, I2C) to be found. Issue 3 is the
most interesting of all.

Newsgroup ucam.cl.risc-ix-users - a few brief and largely uninteresting threads from
this University of Cambridge Computer Lab private newsgroup (articles locked
as they were never intended for public distribution).

Serial port
opto-isolator
(description) (G. Taylor). This
opto-isolator is useful if you want to prevent static electricity from
damaging your serial port (G.Taylor says the A5000's serial port is
very sensitive to this) when connecting a peripheral or another
computer.

(Paper) The July/August 1991 issue of Elektor magazine (at least the UK
version) carries a black and white video digitiser project by John Kortink.
The November issue carries a 24-bit colour upgrade to this.John's site now has these scanned.
